Yes, I want more than WhatWG, and not just that.
WG21 is not in the business of specifying character encodings, so we'd need
to refer to another standard for the details of each encoding.
> Please name a particular encoding that isn't covered by WhatWG, and point to the location of its specification.
What are you talking about?
WhatWG isn't an authority on ANY of those encodings.
You know the iso-8859-XYZ is a standard setup by ISO. Utf-X is defined by the Unicode standard, the windows-Z also have supporting documents setup by Microsoft.
The IANA list has references to the specs of the encoding defined by their enumeration.
Why are we still having this discussion?
